Abstract Cerium-doped lutetium-yttrium oxyorthosilicate (Ce:LYSO) is a well-known single crystal scintillator used in medical imaging and security scanners. Recent development of high power UV LED, matching its absorption band, questions the possibil

The extraction efficiency and the brightness are critical parameters to increase the performance of luminescent rectangular slabs such as scintillators, luminescent concentrators, or diamonds with NV centers. This work explains how an additional face

The LED-pumping technology is used for the first time, to the best of our knowledge, to develop a complete master oscillator power amplifier (MOPA) system including a multipass amplifier. A pumping head using an original slab architecture is develope

We report the development of a high-brightness, high-power Ce:YAG luminescent concentrator pumped by 2240 blue LEDs in quasi-continuous wave operation (10 µs, 10 Hz). Using light confinement and recycling in the three space dimensions, the parallele

Transition metal-doped gain media such as Ti:sapphire, Cr:LiSAF and Alexandrite are the most appropriated crystals for femtosecond laser chains with pulse duration below 100 fs. However, because of a low gain and an absorption band in the green/red r
